That doesn't have the stagefright patch does it? Also wasn't the overclock for our devices ruled as a placebo? I thought that was why Bad_MOFO removed it from his custom rom kernels.
If you're paranoid about about stagefright just throw this at the end of your build.prop and reboot; be very careful of editing the build.prop though.
